RADIATOR.

s'PEc'ImcATIoN forming .part of Letters Patent No. 689,844, dated D c-6mm 31, 1901.

Application filed February 23, 1901- Serial No. 48,606. (No model.)

To aZZ whom it may concern:

Be it known that I, FRANCIS SPENCE BAKER, architect, a subject of the King of Great Britain, residing at Toronto, in the county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Radiators, of which the following is a specification.

Y My invention relates to improvements in all forms of steam or hot-water director indirect radiators; and the object of my inven-' tion is to preferably provide each section of a radiator with an evaporating-chamber; and it consists, essentially, in forming in eachradiator-section, preferably by means" of casting, so as to form an integral part thereof, an air communicating evaporating-chamber having no communication with the heating portion or chamber of the steam or hot-water radiator and providing automatic. means for regulating the supply of water to said evaporating-chamber of the radiator, as hereinafter more particularly explained.

Figure 1 is in part a vertical section through a radiator constructed in accordance with my invention. Fig. 2 is a vertical section through a single section of a radiator constructed in accordance with my invention. Fig. 3 is a diagrammatic view of a radiator constructed in accordance with my invention, showing an automatic means for supplying water to the evaporating-chamber of vthe same. Fig. 4. is a vertical section through a single section of a radiator constructed in accordance with my invention, showing an alternative form of evaporating-chamber. Fig. 5 is in part a ver-' tical section through a radiator constructed in accordance with my invention, showing only one outlet for the evaporating-chamber.

In the drawings like letters of reference in dicate corresponding parts in each figure.

A is the radiator, which is made up of any suitable number of sections B, constructed in any of the well-known ways. In the radiator shown C is the supply-cock for the steam or hot water for the radiator, and D the exhaustcock' for same.

0 represents the legs of the radiator.

The radiator-sections B communicate with each other by means of the nipples E, of any suitable form.

In carrying out my invention I preferably seen from the drawings.

cast near or at the top portion of each section B an evaporating-chamber F, which has of necessity no communication with the heating-chambers F of the said radiator-section.

with the wall F and heating same) escapes into the room. The aperture G will of course be placed in the chamber Fso as to be above the level of the water therein. rating-chamber F of each section is connected to the evaporating-chamber of-the adjacent radiator-section by means of any of the wellknown means, such as nipples E, as will be The nipples E or other connections are preferably flush with the bottom of the evaporating-chambers F, so that the same may be easily cleaned. It will be understood that the evaporating-chambers F, connected together as described, form one large evaporating-chamber G. It must be understood that, for instance, if I construct one of the sections B with an evaporatingchamber F which is not provided with an aperture G the next evaporating-chamber, or, if desired, any desired one or number of them, will be provided with an aperture G, so that the evaporation may escape therefrom, as will be understood. From this it will be understood that, if desired, the evaporating-chamber G may be provided with only one aperture G for carrying off the'evapo'ration; but it is preferred to provide the evaporatingchamber F in each section B with an aperture G, so that the distribution of the moisture into the air will be more uniform, as will be understood. The evaporating-chambers G are preferably formed with a semicircular lower portion, as will be seen, so that when they are all connected together they will form a trough H, which will be kept automatically filled with water to, for instance, the height shown by dotted lines.

I is a water-supply pipe leading from any suitable automatically-operated tank J to the The evapoevaporating-chambers G and opening into the same on a level with the bottom of the trough H, as will. be understood.

K is the supply-pipe of the tank J.

In order to provide for ready cleaning of the trough H, I provide a suitable cap 0, preferably screwed onto one end of the evaporatingchamber G, which can readily be removed by disconnecting any suitable coupling P. The couplingPop'ens from the evaporating-chainber G on a level with the bottom of the trough II and connects with the exhaust-pipe Q.

R is a stop-cock in the pipe Q. It will be readily understood that when the evaporating-chamber G is in operation the cock R is closed. In the supply-pipe I is a stop-cock i. \Vhen the evaporating-chamber G is to be cleaned, the stop-cock 2' is closed and the ,cock R is opened in order to allow the water in the evaporating chamber G to be drawn oif before the cap 0 is removed for further cleaning.

It will of course be understood that the wellknown float M in the tank J automatically closes the well-known valve N in the pipe K, so as to prevent the water in the tank J (and consequently in the evaporating-chamber G, as the water therein will always be at the same level as the water in the tank J) from rising beyond a certain level. In case the water in the tankJ should rise too high the surplus water will be carried off by the pipe L.

I of course do not confine myself to placing the wall or diaphragm I in any particular portion of a radiator-loop, nor do I confine myself to any particular shape of the same nor of the evaporating-chamber F. In Fig. 4t will be seen a cross-section of the wall or diaphragm F shown in alternative form. This diaphragm may be fiat, as shown in dotted lines; but it is preferred to make the same with a trough H. I may also provide each radiator-section B with any desired number of evaporating-chambers F, as will be understood.

' My improvement in radiators is more particularly applied to cast-iron hot-water or steam direct or indirect heating radiators, although wrought-iron or other classes of radiators can be by ordinary mechanical ability fitted with an evaporating-chamber such as I claim.

From this specification will be understood thoroughly my invention; but I do not confine myself to the construction described, and shown in the drawings, which may be altered in many ways without departing from the spirit of my invention.

\Vhat I do claim as my invention, and desire to secure by Letters Patent, is-
